The Caribbean coral reef is home to more than 2,000 sea creatures from 140 species, including turtles and sharks. That’s double the number of animals it previously held.

The tank’s windows have been replaced with a clear acrylic, and the frames have been expanded to offer better glimpses into the underwater world. The top of the tank has been transformed with a new education center.

Aquarium officials say the goal is to enhance the facility’s physical appearance and to bolster educational and conservation missions.
